   Right, otherwise people would complain a lot more about ksh than
   they currently do looking at the web...

I'm pretty sure I have shell scripts that rely on /dev/fd/N working as
an exec'd command argument for N > 2.  An example of an exec'd program
that uses N > 2 without /dev/fd/N is gpg, with the --passphrase-fd,
--command-fd, --status-fd options.  I would be unhappy if these broke.

...unless I've misunderstood what this thread is about from my very
cursory skimming of it.
